Question to the Department for Transport:

To ask Her Majesty's Government what provision has been made to facilitate the interchanges at Old Oak Common station between (1) HS2, (2) Crossrail, and (3) Great Western Railway, services; what are the estimated costs and sources of funding for those provisions; and how long they estimate any (a) closures, and (b) disruptions, of (i) Crossrail, and (ii) Great Western Railway, services to last during construction.

The proposal for Old Oak Common is for an integrated station consisting of six HS2 platforms and eight platforms for the existing rail network, providing passengers with a direct interchange between high speed and conventional rail services. The estimated costs of delivering the station are contained within the reset Phase One estimate, which forms the basis of the Full Business Case for HS2 Phase One which was approved in April of this year.

The final design and precise construction programme for the station, which will determine the impact of Old Oak Common construction on existing services, is still being developed by HS2 Ltd and the Old Oak Common Station Construction Partner, Balfour Beatty Vinci Systra (BBVS). The construction programme is being developed in consultation with the wider rail industry and every effort is being made to minimise disruption to services on the Great Western main and relief lines.
